How to Swish
As guests arrive, add their items to the growing pile of goodies.
Invite guests to spend some time rifling through the goodies ladi out over a glass of wine.
Decide on the starting time for the swish - maybe an hour or so after guests arrive.
Once most of the people have arrived, explain the rules and announce the start time.
Give a five minute warning for the start of the swish.
Countdown to the Opening of the Swish.
When it opens, whatever people take is theirs.
Everyone must bring at least one item of clothing; peole can leave with as many items as they want.
No one can claim items as their own before the swish opens.
And, no scrating, spitting or biting!
